I'm sorry if there is any confusion when stating the purity.
Actually, for IGF1 LR3/DES, our quality control line is purity > 95%, if any batch doesn't meet the spec, it is abandoned (checkout our youtube channel for how we test our products
LabpePeptide - YouTube , new video clips are adding one by one). In reality, the purity of IGF may vary from 96%-99%.
Our statement claiming to be the top quality is not only just words, but it is also backed up by video proof.
Thanks
